If 3x + 7 = 16, what is x?

To solve the equation (3x + 7 = 16), we begin by isolating the term with (x). First, subtract 7 from both sides of the equation:

[ 3x + 7 - 7 = 16 - 7

]

This simplifies to:

[ 3x = 9 ]

Next, to solve for (x), we divide both sides by 3:

[ x = \frac{9}{3} ]

This further simplifies to:

[ x = 3 ]

Thus, the value of (x) that satisfies the equation is 3. The chosen answer corresponds with this calculation, confirming that (x = 3) correctly aligns with the original equation. The procedure followed ensures that the solution adheres to algebraic principles by isolating (x) systematically.
